4. Konfigurazioa eta instalazioa
Segurtasun-ohar garrantzitsua: Installation should be performed by qualified personnel. Ensure power is disconnected before wiring to prevent electric shock. Strictly distinguish between power supply, sensor, and relay interfaces. Maintain proper distance between sensor down-lead and power wires to avoid interference.
4.1 Kableatu-diagrama
Refer to the following diagram for correct wiring connections. This model operates on DC 12V power supply.
3. irudia: Wiring diagram for the STC-1000 12V temperature controller. Connections are for power supply, NTC sensor, heating relay, and cooling relay.
- Terminals 1 & 2: Power Supply (DC 12V).
- Terminals 3 & 4: NTC Sensor connection.
- Terminals 5 & 6: Heating Relay Output (Connect to heating device).
- Terminals 7 & 8: Cooling Relay Output (Connect to cooling device).
Ensure all connections are secure and insulated. Verify the power supply voltage matches the controller's requirement (DC 12V for this model).
4.2 Muntaketa
The STC-1000 is designed for panel mounting. Cut an opening of 71mm x 29mm in your panel. Insert the controller and secure it using the provided clips or mounting brackets.
5. Funtzionamendu-argibideak
The STC-1000 operates in Celsius only. It cannot be switched to Fahrenheit.
5.1 Piztu/Itzali
- Sakatu Pizteko etengailua button (marked with ⏻) to turn the controller on or off.
5.2 Tenperatura-parametroak ezartzea
The controller has two main temperature settings: the Set Temperature (ST) eta du Difference Temperature (DT), also known as hysteresis.
- To view the Set Temperature (ST): Sakatu labur Setting (S) button. The display will show the current set temperature.
- To modify the Set Temperature (ST):
- Eduki sakatuta Setting (S) botoia sakatu 3 segundo inguru, pantaila keinuka hasi arte.
- Erabili GORA (▲) or BEHERA (▼) buttons to adjust the desired set temperature.
- Sakatu Pizteko etengailua button to save the setting and exit, or wait for 10 seconds for it to save automatically.
5.3 Advanced Parameter Settings (F1-F4)
Parametro aurreratuak atzitu eta aldatzeko:

5.4 Heating and Cooling Modes
The STC-1000 automatically switches between heating and cooling based on the set temperature (ST) and difference temperature (DT).
- Hozte modua: If the current temperature is higher than (ST + DT), the cooling relay activates. It deactivates when the temperature drops to ST.
- Berokuntza modua: If the current temperature is lower than (ST - DT), the heating relay activates. It deactivates when the temperature rises to ST.
6. Mantentzea
- Garbiketa: Wipe the controller's surface with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Sentsoreen zainketa: Ensure the NTC sensor probe is clean and free from debris. While waterproof, avoid unnecessary physical damage to the probe or cable.
- Konexioak: Periodically check wiring connections for tightness and signs of corrosion.
- Ingurumena: Operate the controller within the specified ambient temperature and humidity ranges to ensure optimal performance and lifespan.
7. Arazoak
| Arazoa | Kausa posiblea | Irtenbidea |
|---|---|---|
| Display shows "EE" | Sensor error or open circuit. | Check sensor connection. Replace sensor if damaged. |
| Display shows "HHH" | Temperature exceeds upper limit of measurement range. | Ensure the environment temperature is within the sensor's range (-50°C to 99°C). |
| Display shows "LLL" | Temperature falls below lower limit of measurement range. | Ensure the environment temperature is within the sensor's range (-50°C to 99°C). |
| Kontrolagailua ez da pizten | Ez dago energia-iturririk edo bolumen okerratage. | Check power connections and ensure DC 12V is supplied. |
| Berokuntza/Hoztea ez da aktibatzen | Incorrect temperature settings (ST, DT), wiring error, or device malfunction. | Verify ST and DT settings. Check heating/cooling device wiring. Ensure the device is within operating parameters. |
